"With this punch I wanted to re-create classic tiki flavors," says bartender Erick Castro. "They highlight the botanicals in the gin and the playful funkiness you can only get from Jamaican rum." The drink's uncommon garnish—a pinch of cinnamon—accents the rum.

When he's grilling for pleasure on a hot summer night, Francis Mallmann invariably has a cool cocktail in his free hand. The extra-refreshing one here combines sweet wine and the bitter Italian aperitif Campari.

Of course Maria Helm Sinskey and her husband, Rob (co-owner of Napa's Robert Sinskey Vineyards), serve their wine at parties. But she also offers refreshing punches like this one, made with tart-sweet pomegranate juice and finished with Prosecco.

This sangria-like drink is a cobbler—a classic cocktail combining some kind of liquor or wine with sugar and fresh fruit. John Salas spikes his with a vinegar syrup called a shrub, for a tart, refreshing, complex edge.

Instead of combining vodka with flavored Jell-O mix, Michael Symon concocts a refreshing mojito and stirs unflavored gelatin into the mint-and-lime-spiced rum drink to mold a fun and sophisticated version of the lowbrow shot.
